The Twinkles, ages 8 through 12, train at the World Cup All Stars Gym in Freehold, where they are redefining what it means to be a cheerleader. Forget right now about what you see on the sidelines at football games. This is cheerleading as a high-flying sport whose soaring participants work like professionals, often devoting six or seven days every week to training.

They attend formal practice on Sundays, Tuesdays and Thursdays, take private lessons and flock to the gym for open tumbling sessions. Not even the slightest flaw is tolerated — they will repeat their 2-minute, 25-second routine with mind-numbing devotion for six months before performing it in front of an audience.

During the second day of the Athletic Championships on Jan. 29 in Providence, R.I., Gianna Antico and her stunt group take their turn practicing stunts in a small convention hall room.

But the Twinkles also act their age, chatting about "Toddlers & Tiaras," how much they hate hair spray and how blueberries turn their teeth purple — all while doing backflips.

"Cheerleading’s taken over the world," World Cup co-owner Elaine Pascale says. "It’s on TV. It’s in magazines. Our community has really grown to be very, very vast as far as encompassing a lot of lay people that never knew such a thing existed."

The girls are aware they are phenoms, devoting their unnaturally chiseled bodies, their time, their emotional capacity and their parents’ money — some more than $10,000 a year — to being the best. Because when you’re a Twinkle, nothing else matters.

Lauren Preston gets some help stretching from her mother, Lori, as other Twinkles look on and her teddy bear sits nearby at the Rebel Classic Cheer Championship at Howell High School on Jan. 15. The teddy bear, which she has had since birth and goes everywhere with her, was always close by, until she lost it on a competitive trip to Florida later in the season.
